    Abstract: A seed delivery device including a frame defining at least one seed chamber. The frame includes a sidewall and an air permeable floor. Seed can be received and deposited on the air permeable floor through an input port. An air input channel is utilized to introduce an air stream into the seed chamber and direct it through the air permeable floor such that seed is lifted from the air permeable floor to an outlet port. An air bypass channel is configured to separate the air stream into a first stream that is directed through the air permeable floor and a second stream that is directed through the bypass channel and recombined with the first stream, at a point prior to the output port.

    Abstract: A seed metering system, for use on a row crop planter, selects individual seeds from a seed reservoir and dispenses the seeds singularly at a controlled rate. A direct drive seed metering system includes a seed disc having a plurality of suction apertures with a recessed pocket adjacent to an aperture. The recessed pockets act to agitate seeds in the seed reservoir and to direct seed flow towards the apertures. A seed path relief system provides for allowing the placement of the seeds such that they are released from an outer edge of the seed disc. An adjustable seed singulator is mounted adjacent to the face of the seed disc where inner and outer blades are adjusted radially to compensate for the singulation of various seed sizes and shapes. The seed disc is driven via engagement of an internal gear with the external gear of an independent drive motor.

    Abstract: An agricultural implement is provided that includes a number of row units. The row units include one or more seed meters for receiving, singulating, and dispensing seed to the ground such that preferred spacing of subsequent seed is attained. Seed delivery systems are included to aid in transporting the seed from the seed meter to the ground in a controlled manner to mitigate skips and to aid in controlling the spacing of the seeds, which can be based upon the ground speed of the implement as it moves through the field. The seed delivery systems can control the transport of the seed to a furrow in the field such that the seed can experience zero or near zero relative velocity so that the seed will have little to no movement once positioned in the furrow.

    Abstract: An agricultural planter includes a plurality of row units attached to a toolbar. The row units include seed meters in seed meter housings for receiving, singulating, and dispensing seed or other particulate. The seed meters include a circular seed disc with a seed path for receiving the seed in the seed meter housing. Integrated with the seed meter, such as at the housing, is an electric pressure source dedicated to create a pressure differential for the seed meter or meters at a particular location on the planter. The pressure source can be positive or negative to temporarily adhere seed to the seed disc of the meter. A single pressure source can provide the pressure differential to a single meter or to multiple meters or discs at a row unit.
